The Dallas Cowboys conducted a little business in advance of Saturday's preseason opener at Los Angeles.

The team has agreed to terms with center Travis Frederick on a six-year contract extension that will make him the highest-paid center in the league, NFL Media's Rand Getlin and NFL Media Insider Ian Rapoport reported on Saturday. Per Rapoport, the deal is worth $56.4 million ($18.2 million fully guaranteed, $28.2 million in total guarantees), per a source informed of the contract.

The 2013 first-round draft pick's four-year rookie deal was worth $6.87 million. The Cowboys had already exercised the fifth-year, $8.8 million option on his contract for 2017.

After opening contract talks with one of the NFL's best centers earlier this month, executive vice president Stephen Jones noted that Frederick is "one of those guys you want on your football team."

"I don't know how many different ways we can say it, but it's the strong point of our football team," Jones said, via ESPN.com, of the offensive line. "The strength of it and the amazing thing about it is it's not only a strength in terms of on the field, but they represent everything we want in terms of the work ethic and what they do off the field. So just a great group to try and (we will try to) keep them all together."
